'DETACHABLE WHEEL-RIM.

' T 0 all whom it may concern:

Be it known that l. Jon J. Brnxrr. a citizen of the United States. residing at Shreveport, in the parish of (.addo and State; of Louisiana, have invented certain new .and'useful Improvements in Detach able lVheel-Rims, of which the following is a specification.

This invention relates to vehicle wheels.

and more particularly to wheels having de tachable rims and adaptedprimarily for use in conjunction with motor \'e h1cles.

The object of the present invention is to provide an improved device of the character set forth in which the several parts arefirnily locked together. and in which the rim portion has an efficient driving connection with the spoke carrying portionto adapt the-structure for efficient use upon a rear or driving wheel of a motor vehicle.

Forther objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing Figure 1- is a side elevation of a wheel constructed 1n accordance with the invention. Fig. 2 is an enlarged sectional view therethrongh. Fig.

3 is a front elevation of the inner or spokecarrying portion of the wheel. Fig. 4: is an edge elevation of said spoke carrying portion. Figs. 5 and 6 are detailed sectional views illustrating locking members hereim after described. Fig. 7 is a face-view of a locking ring. Fig. 8 is a sectional view through said locking ring. Fig. 9 is an edge'view of a tire retaining flange. and Fig. 10 is an-edge View showing said flange mounted upon the rim, the parts in this 'figure being shown upon a larger scale. 40-

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing numeral!) designates the spokesof the wheels upon which is mounted a fixed rim member 6. The rim member 6 is provided with a flange 7 at its rear face. said flange carrying stop members 8 which "enter recesses formed in the rear face of a (lemountable rim 9 to thereby provide a driving connection between the fixed rim and the demountable rim. A pneumatic or other tire indicated at 10. and

the construction of which is too well known to require further description. is held in place between a fixed flange 11 of the demountab'ie rim 9 and a flange 12 of a ping Specification of Letters Patent. PafentedJun 25, 1912. Application file d December 19. 1911. Serial'No. 666,698.

lsee Fig .'2. 10-and 11) is provided with an inwardly projecting lug 14. having a slot 15 formed therein. This slot 15 is adapted to receive the bent over end 16 of a latch 17 (see Fig. 5). It is apparent that if the latch is turned by manipulating its head 18 before the parts are assembled. to bring the end 16 into longitudinal alinement with the slot'li'i. a-spring 19 will depress the latch until its end lit-is free of lug 14. at which time. and not until then. a partial rotation may be imparted to ring 13 with rela'tionto the deniountable rim't). .Ring 13 is provided with lugs 20, one of which is shown in Fig. 2. These lugs are adapted to travel transversely-in slots 21 (see Fig.1) in' plac- 'ing the ring 13 in position. After the ring has moved inwardly to the proper point, it may be'g'iven a partial rotation with relation to the demount aole rim 9, the l1tgs-20 at this time traveling in longitudinal slots 22 which are continuations of slots 21 (see Fig. 10). It will, tl1eref0re,'be understood that through theinedium of ring 13 the tire is first secured uplon the demountable rim,

and that means, ereinafter described, are

then employed for securing the demountable rim upon the rim 6.

TlheanherLperipheral face of the demount a'ble rim 9 1S beveled at 23, and the outer peripheral face of the fixed rim is oppositely beveled at 24 and between these beveled surfaces a locking ring 25 is placed, having its inner and outer peripheral faces oppositely beveled to correspond with the beveled faces 23 and 2t. Thefixed rim 6 carries a pinion 26 to which rotation may be imparted by the application of a key (not shown) to the F angularshat't 27 of said pinion. This pinion meshes with an internal rack 28 formed upon the inner peripheralface of ring 25' (see Figs. 3. T and 8). The ring 25 carries inwardly directed lugs 29 adapted to pass inwardly through openings 30- and to then engage behind and be forced inwardly by cam faces31 when said ring is partially rotated with relation to theffixed rim. 6.

This partial rotation may be imparted to the locking ring through themedium of' pinion 26, as will be readily understood; A locking device for locking the .ring .25 against rotation with relation to, thefixed rim 6 is illustrated in Fig. 6. This locking device comprises a latch 32; normally down-.-

' wardly pressedfby, a spring"33'zan'dhaving n ,L-sha1')ed"'end 34"adapted toengage in a recess 35 of ring. 25. It is apparent.

from an inspectionof 6" that when the latch is turned to bring the end 34 into transverse alinement with therim' 6, the latch will be held an elevated and locking wposition, asvshownj' but when the end 34 is turned into longitudinal alinement with the wheel, the latchdescends until it lies ent-irely within the rim 6 and permits rotation of ring 25. By virtue of the double wedgi'ng 'faces '23 and 24 and thelcorrespon'ding wedge facesupon ring-25, it is apparent thatwhen rotation is imparted'torthe ring and the; ring ;isgdraw'n inwardly by the engage- I'nent of its lugs 29 with the cam faces, 31, a

tight engagement between all of the parts is had,,and sincethe' stop members 8 are at this time engaged with the demountable rim 9,

' it is apparent that this in conjunction with the tremainder'of the structure provides an eflicient driving connection between the fixed; rim and the demountable rim. 7

From the foregoing description it willbe seen that simple vand eflicient means are herein provided toraccomplishing the objects of the-invention, but while the eled inents shown and described are well adapted to serve theipurposes 'for which they are intended, it is to be understood that the invention is not-limited to the precise construction set forth; but includes within its purview suchchanges asmay be madewith inthe scope of the appended claim.

Having described .my invention what I claimis:

In a demountable wheel rim, the combination with a fixed annular rim member having an, inner edge outstanding flange and having its outer peripheral face inilined away from said flange and toward th axis of the wheel, said beveled face being cut; away to form a plurality of cam faces; an annular demountable rims having its inner peripheral face oppositely inclined from that of the fixed rim member and having a portion extending inwardly of and bearing upon its outer periphery shoulders coacting with the shoulders of the demountable rim and having upon its inner periphery an in- 7 wardly extending annular flange which overlaps the. outer face of the fixed rim member, and means carried by ,saidlocking ring for engaging said cams.

In testimony whereof I aflix my signature 65 in presence of two witnesses. i JQE J. BURNEY.
